1 Claim. 1

My present invention relates to apparatus for use in connection withroll-making machines of the general type used in bakeries and has forits main object the spraying of diVidiIlg oil on the scaled dough piecespassing through the machine, thereby rendering the machine free fromsticky or hardened dough particles which otherwise adhere to variousparts of the machine both while in operation and idle.

Another object is the provision of a gravity feed oil dispensingreservoir adapted for suitable mounting on the machine, the reservoirbeing provided with an auxiliary gravity oil feed conduit, an emergencygravity oil feed conduit, and a main gravity oil feedconduit which hasassembled in connection therewith, an air feed conduit having a sprayhead member and adapted for assembly with an air compressor unit housedin the base of the machine.

A further object is the provision of regulating valves for each of theoil feed conduits and for the air feed conduit to insure the requiredquantitative flow of oil and air for the machine in use.

Other objects and advantages will appear from the followin descriptionand reference to the accompanying drawings, in which:

Figure 1 is a side elevation of my present invention shown in full lineand mounted on a roll-making machine which, not being a part of myinvention, is shown in dotted lines, and the lower portion thereof isbroken away to conserve s ace.

Figure 2 is a top plan view of Fig. 1, a portion at the right-hand endthereof being broken away to conserve space.

Figure 3 is an enlarged detail view, the top and bottom ends being insection, showing the oil spray assembly.

Figure 4 is a perspective view taken from beneath the assembly shown inFig. 3, showing more clearly the general shape and contour of the same.

Referring now to the drawings and having first reference to Fig. l, thedotted lines indicate generally the roll-making machine, the basehousing being indicated by the letter A, the dough tank by the letter B,the revolving rounder bowl by the letter C, the stationary spiral memberby the letter D, and the revolving turn-table by the letter E, and it isobvious that a showing of the various parts of the machine is omitted,save in the case of such parts as have a direct connection orassociation with my invention.

In the Figs. 1 and 2 it will be noted that the ber IQ of the spray oilreservoir'bears the numeral l0 and it is shown vertically mounted on theside of the dough tank B by means of the horizontal bracket members II.On the top of the oil reservoir 10 is provided the oil filling port 12having a removable vented cap 13.

Depending centrally from the bottom of the oil reservoir is therelatively short gravity feed oil pipe I4 having its lower end formed soas to project outwardly from the reservoir I 0 and connect with theregulatin valve l5 from which depends the emergency oil feed conduit I 5arranged to provide oil on the stationary spiral member D in case themain oil feed conduit l8 becomes momentarily clogged.

Mounted on the opposite sides of the regulating valve l 5 are tworelatively short oil feed conduits l6 and I1 having mounted on theirouter ends the regulating valves Hi and H respectively which in turnhave depending therefrom the auxiliary oil feed conduit Ni and the mainoil feed conduit I 1* respectively. The conduit l6 directs oil to thesurface of the turn-table E, and the conduit ll directs oil to the tubememunit assembly I 8; said tube member I!) being connected to the upperend of the conduit I! by means of the cap member 20.

It will be noted, particularly in the Fig. 3, that said oil tube memberl9 connects at its lower end to the nozzle fitting 2| in which thehorizontally disposed orifice 22 registers in line with and forms aconduit connection with a similarly arranged orifice 23 in one side ofand intermediate the top and bottom of the nozzle member 24 protrudingdownwardly from said nozzle fitting 2| and in connection with the airtube member 25 which is connected to the compressed air feed conduit 2!by the cap member 26.

'I he structure and arrangement of the spray unit assembly !8, withparticular reference to its assembled relation to and connection withthe spray nozzle 24 discloses the unit character thereof, and thespraying of oil therewith is accomplished by means of compressed air(from a compression tank not shown but mounted within the housing A ofthe roll-making machine), being forced from the relatively small orifice28 centrally in the outer end of said nozzle 2d, and the subsequentsuction which draws a certain amount of oil through the aligned orifices22 and 23 into the air stream through the bore 29 and out of the orifice28 of the nozzle 24 in the form of oil spray indicated at X, whichdirects a very thin coating of dividing-oil on the dough pieces as theyare propelled along the It is obvious too, that by means of the regulat-I ing valves l5, Hi and H the amount of oil flow from the oil feedconduits [5 216 and Il may be fixed at the will of the operator inaccordance with the requirements of the machine with respect to varioustypes and sizes of scaled dough pieces being handled therethrough. 7

It is here pointed out that inasmuch as the air feed conduit and oilfeed conduits of my invention are of such metal as facilitates the readyforming and shaping thereof to meet the physical requirements of varioustypes of roll-making machines, the same is in no way limited to the typeof machine indicated generally by the dotted lines in the accompanyingdrawing. And it is also pointed out that any suitable means may beadopted for mounting the spray unit [8 on the various types of machines,although simple and well known clamping devices have been convenientlyand successfully used for the purpose.

The roll-making machine forming no part of my invention, it is thoughtthat further descriptive details referring to the structure andoperation of said machine are unnecessary to a clear understanding of myimproved apparatus for the purpose herein set forth.

While I have illustrated and described one particular embodiment of myinvention, it will be apparent to those skilled in the art that theprinciple thereof may be utilized in other embodiments. I do not,therefore, present my invention as being limited to the herein disclosedembodiment.

Reference to the appended claims will de termine the scope of thepresent invention.

What is claimed is:

An apparatus of the character herein described comprising in combinationa gravity feed reservoir for containing dividing oil, a plurality ofregulator valves connected by a conduit to the reservoir and adapted asdeterminants to provide sustained flow of oil in connection with aroll-making machine, a conduit member connected to one of said regulatorvalves to direct the dividing oil to a point within a part of themachine, a conduit member connected to another of said regulator valvesto direct said oil to a point on a part outside of the machine, and aconduit member connected to still another of said regulator valves todirect said oil to an oil spraying element adapted to spray dividing oilat a point within a part of the machine, a conduit member adapted toconvey air under compression to said oil spraying element, a regulatorvalve and an air pressure indicator connected with said air conveyingconduit member, a spray nozzle member in said oil spraying element, abore open'inglongitudinally through the spray nozzle and a side openingin the nozzle, said side opening in aligned communication with acorresponding opening interiorly of the oil spraying element to eiTectthe spraying of a regulated quantity of oil from the spray nozzle memberby. means of compressed air for the purpose of directing a spray ofdividing oil on dough pieces carried by the mechanism of said machinepast the spray nozzle of said oil spraying element.
